Which essential nutrient helps the body produce energy and regulate metabolism? B vitamins help perform those jobs. This group of water-soluble vitamins supports enzymes that break down carbohydrates, fats, and proteins and turn their chemical energy into forms cells can use.
The B-complex family includes eight vitamins: B1, B2, B3, B5, B6, B7, B9, and B12. They do not supply calories themselves, but several act as coenzymes in metabolic pathways. Folate and vitamin B12 are also important for DNA production and healthy red blood-cell formation, while B6 contributes to amino-acid metabolism and nerve function.
A common misconception is that taking extra B vitamins automatically creates more energy or replaces sleep and food. They help normal metabolism, especially when a person is deficient, but supplements do not work like stimulants. Most B vitamins are not stored extensively in the body, although vitamin B12 can be stored for years.
